NAME
ckkeywd - prompts for and validates a keyword
SYNOPSIS
ckkeywd [-Q] [-W width] [-d default] [-h help] [-e error]
[-p prompt]
[-k pid [-s signal]] [keyword [...]]
DESCRIPTION
ckkeywd prompts a user and validates the response. It
defines, among other things, a prompt message whose response
should be one of a list of keywords, text for help and error
messages, and a default value (which will be returned if the
user responds with a carriage return). The answer returned
from this command must match one of the defined list of key-
words. All messages are limited in length to 70 characters
and are formatted automatically. Any white space used in
the definition (including newline) is stripped. The -W
option cancels the automatic formatting. When a tilde is
placed at the beginning or end of a message definition, the
default text will be inserted at that point, allowing both
custom text and the default text to be displayed. If the
prompt, help or error message is not defined, the default
message (as defined under NOTES) will be displayed.
-Q Specifies that quit will not be allowed as a valid
response.
-W Specifies that prompt, help and error messages will be
formatted to a line length of width.
-d Defines the default value as default. The default is
not validated and so does not have to meet any cri-
teria.
-h Defines the help messages as help.
-e Defines the error message as error.
-p Defines the prompt message as prompt.
-k Specifies that process ID pid is to be sent a signal if
the user chooses to abort.
-s Specifies that the process ID pid defined with the -k
option is to be sent signal signal when quit is chosen.
If no signal is specified, SIGTERM is used.
keyword
Defines the keyword, or list of keywords, against which
the answer will be verified.
